System and method of accessing and recording messages at coordinate way points

Abstract

The present invention is essentially a method and system for leaving and retrieving messages at specific coordinate way points within a commercial mobile radio service (CMRS) provider network. Users carry or transport interface devices for communicating over the network and are able to record and view messages at specific coordinate locations while traveling in the network. The location of the device is calculated by the device or by the network while the device is powered on and in within the physical boundaries of the network, or through a combination of both. Messages can be made available to network subscribers when their interface devices come within an area centered about a physical coordinate location. Personalized messages can also be left by subscribers at any coordinate point within the boundaries of the network. The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximity threshold relative to said asset.

Description

[0001] This application is a Continuation in Part of U.S. patent application Ser. No. 10 / 102,325 filed Mar. 20, 2002 entitled "System and Method of Accessing and Recording Messages at Coordinate Way Points" which is a Continuation of U.S. patent application Ser. No. 09 / 732,170 filed Dec. 6, 2000 now U.S. Pat. No. 6,377,793 issued Apr. 23, 2002 entitled "System and Method of Accessing and Recording Messages at Coordinate Way Points."INVENTION[0002] The invention is essentially a system and method for accessing and leaving messages at physical coordinate way points. Using hand held, user supported, or car mounted wireless computing and / or Communication Devices, users can either leave or access messages which become available by virtue of the physical coordinate location of a wireless network Subscriber's Device.[0003] As our society continues to evolve and become more integrated with technology demand for wireless information increases constantly. Mobile phones, pagers, personal Commu...

Benefits of technology

0004] Cellular and wireless networks are also capable of delivering this kind of position information to their subscribers. Through Triangulation, signal strength measurements, angle of incidence measurements, GPS over cellular, and combinations of these techniques, cellular networks can pinpoint the location of a driver to within reasonable levels of accuracy. Especially in densely populated areas, where there are many cellular towers within close proximity to one another, it is possible to determine, within tens of meters of accuracy, the location of a user of a cellular phone.

0005] In 1998, the Federal Communications Commission (hereinafter FCC) mandated in its rules for commercial mobile radio service (herein after CMRS) providers that the providers upgrade their networks to facilitate emergency 911 or E911 service, requiring them not only to connect the calls to the appropriate operator and transmit the caller's phone number, but also to transmit position information on the origination point of the call. The Commission adopted E911 rules in accordance with an agreement between the wireless industry and state and local 911 officials to promote wireless technologies and transmissions that provide important information to enable the 911 Public Safety Answering Point (PSAP) to promptly locate the 911 caller. The wireless E911 service was established to ensure that wireless phones automatically transmit the same vital data about a 911 caller's location as wireline phones. CMRS providers were expected to achieve transmission of the enhanced location information in two phases, with Phase I to begin Apr. 1, 1998. Accordingly, the E911 rules now provide that, for Phase I, carriers transmit a caller's Automatic Number Identification (ANI) and the location of the cell site or base station receiving a 911 call to the designated 911 PSAP beginning Apr. 1, 1998. These capabilities allow the PSAP attendant to call back if the 911 call is disconnected and to provide general location information to assist in the prompt dispatch of emergency personnel.

Problems solved by technology

The problem with GPS is that a separate receiver is needed to receive the satellites' signals and that the signal itself is very weak.
